Free Logarithms Calculator - Simplify logarithmic expressions using algebraic rules step-by-step.
31 Ιουλ 2024 · Your favorite tool to calculate the value of log₂ (x) for arbitrary (positive) x. The operation is a special case of the logarithm, i.e. when the log's base is equal to 2. As such, we sometimes call it the binary logarithm. If you wish to discover the more general case, check out our log calculator.
Algebra. Evaluate log base 2 of 8. log2 (8) log 2 (8) Rewrite as an equation. log2(8) = x log 2 (8) = x. Rewrite log2 (8) = x log 2 (8) = x in exponential form using the definition of a logarithm. If x x and b b are positive real numbers and b b does not equal 1 1, then logb (x) = y log b (x) = y is equivalent to by = x b y = x. 2x = 8 2 x = 8.
Examples. \left. \begin {cases} { 8x+2y = 46 } \\ { 7x+3y = 47 } \end {cases} \right. Solve your math problems using our free math solver with step-by-step solutions. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more.
The graph of the logarithm base 2 crosses the x-axis at x = 1 and passes through the points (2, 1), (4, 2), and (8, 3), depicting, e.g., log 2 (8) = 3 and 2 3 = 8. The graph gets arbitrarily close to the y-axis, but does not meet it. Addition, multiplication, and exponentiation are three of the most fundamental arithmetic operations.
